Abstract
Methods for reducing potential pollutants in carbonaceous materials such as coal, lignites and the like prior to utilization such as by combustion, the invention in preferred embodiments processes such materials by resonance disintegration including inter alia subjection to rapid pressure increases and decreases to reduce the materials to particle sizes of a preferable mean value of approximately fifty microns or less. Pollutants such as sulfur, mercury and other heavy metals bound in a mineral fraction and micronized by such processing can then removed by classification techniques based on physical differences between a micronized carbonaceous fraction and the mineral fraction. Combustion of the micronized carbonaceous fraction substantially free of the mineral fraction results in emissions having reduced levels of sulfur, mercury and other toxic substances. The methods of the invention further include removal of water from carbonaceous materials such as coal, lignites and the like by subjection of such materials to resonance disintegration.
